Apr 19, 2021 · Vapor implies the existence of a condensed phase that is the source or destination of the gas, or with which the gas may be in equilibrium; while gas does not make such an assumption.

Jan 23, 2014 · Vapor pressure or equilibrium vapor pressure is the pressure exerted by a vapor in thermodynamic equilibrium with its condensed phases (solid or liquid) at a given temperature in a …

Nov 30, 2022 · 1 What is the difference between "smell/odor" and "vapor" of a substance? It is assumed that the vapor of a given compound/element is the gas phase of the same pure compound/element. …

May 6, 2024 · 1 Think of molecules of water liquid escaping into vapor, and molecules of water vapor condensing into liquid. Both processes occur simultaneously, and an equilibrium is reached in a …

Jan 19, 2025 · 5 The phase with higher vapor pressure would evaporate and condense as the other phase. That is why vapor pressure above both substance condensed phases must be equal at the …

Oct 20, 2019 · The figure below shows how vapor pressure of a liquid is measured. Initially the flask is at atmospheric pressure. Then the liquid is dropped in the flask. Once equilibrium is reached, the …

Sep 22, 2024 · At the right low gas pressure means no liquid; increasing pressure below the critical T eventually induces liquid formation in equilibrium; attempts to increase pressure simply increase …

Oct 16, 2019 · The additional pressure compresses the liquid and thereby increases its chemical potential, resulting in an increased vapor pressure. However, since Vm, l V m, l is relatively small, the …

Dec 31, 2018 · The vapor pressure of a liquid at a given temperature is an intrinsic property due to the equilibrium between the liquid and gas phase of that substance. Vapor pressure does affect boiling …

Sep 25, 2023 · The partial pressure of vapor is approximately equal to (saturated) vapor pressure and the pressure difference to external pressure is compensated by partial pressure of the system air. If …
